MAGAZINE IN BASE-BURNING' STQVES.,

The Schedule rfened to in these Letters Patent and maldng part of 'thesama.'

To all lwhom tt may concern v Be it known lthat we, JASPER VAN WoRuERand MICHAEL MCGARVEY, both of the city-o);` Albany, in the county ofAlbany, and Statepf New York, have invented a new and useful Improvementin Magazines for Self-Feedin g Stoves and we do hereby declare that thefollowing is a full. and exact description thereof, ref? erence'beinghad to the annexed drawings, making a part of this specification, inwhich- Figure 1 is a sectional view of a complete stove having ourimproved magazine or feeder, f

Figure `2 is a perspective view of the magazine or feeder.

Figure 3 shows our method of hanging the feeder in thel steve, so thatit may be adjusted to regulate the discharge of the coal.

Figure i represents our 'method of connecting the twokparts of thefeeder, t'. c., the vreservoir and the nec Like letters refer to likeparts.

A. is the coal-reservoir, having its lower part, C, contracted.

B is the neck, having a flaring mouth-piece, D, attaehed to its upperend.

E E are pins, attached to the outside ofthe flaring mouth-piece D.

F E are notches in the lower edge of the contracted end, C, of thereservoir.

I, iig. 4f, is the portion of this lower edge between :the notches, cuton an incline.

'Ihe dotted line H H, iig. 4, is the upper edge of the flaringmouth-piece D, as it rests on the inside of the contracted end, C.

In self-ieedin g or magazine-stoves, as heretofore constructed, therehave been found several seriousiobje'ctions, arising from the peculiarconstruction of the reservoir.

When the reservoir has been made of the same size throughout its entirelength, or where there has been a slight gradual increase in sizetowards the lower end, it is found that the coal in the reservoirpresses down on the burning mass of coal underneath with too greatweight.

- When the reservoir is constructed with a contracted discharge-end, thecoal is continually choking and clogging up at the outlet, so that itsdescent is not free, often clogging during the night, causing the fireto go out for the want of a supply of fuel. The most tangible reason forthis obstruction is that the heat enters the coal at the lower end ofthe reservoir, where it lies immediately over the burning mass in theiire-pot causing the coal to become expanded, and bind itself fast,forming an arch, so that a poker or iron bar has to be used to force itdown into the lire-pct.

l To obviate and overcome these difculties, we construct a magazine orfeeder as follows:

The upper portion A consists of a reservoir, made large, so as to hold alarge body of coal, and having its lower portion contracted, as shown inthe drawings.

Attached lto this reservoir, and forming the lower part of the yfeeder,is a neck, B, of sufficient length that the reservoir, with the body ofcoal in reserve, shall be placed at such a' distance from theburningcoal as to b'e out of the intense heat. This neck is enlarged at itslower end, giving a free discharge of the coal, with no risk of cloggingor choking. The

enlarging of the neck at its lower end will completely mouth-piece,formed at an angle to correspond with that of the contracted part of thereservoir. The diameter of the upper part of the mouth-piece mustbegreater than that of the lower edge of thecontracted end of thereservoir, so that, while the ,mouth-piece will iit down into thiscontracted end, it will not slip entirely through it, but will besupported by it. In the lower edge of the contracted end of thereservoir are cut three notches, of the same size, and at a uniformdistance apart. Three pins are attached tothe outside of the aringmouth-piece ofthe neck, so as to correspond. with these notches, and toallow of their passing down through the notches. The lower edge of thecontracted end of the reservoir, between each of these notches, is cuton 'an incline, so that, when the neck has been passed down through thereservoir, the pins passing through the notches, the daring mouthpieceof the neck resting upon the inside of the contracted end of thereservoir, by a slight turn of the neck, the pins pass under theinclined edge, and lock the neck and reservoir firmly together.

What we claim as our invention, and desire to secure by Letters Patent,is-

1. Attaching to the ordinary contracted reservoir a neck, having itslower end enlarged, substantially as and for the purpose described.

2. The method of attaching the neck to the reservoir, :substantially asset fort JASPER VAN WORMER.
